To all 'whom-it may concern :v

.Be it known that we, ALLEN P. MEAKER and IRA F. BAKER, citizens of thevUnited States, residing at SanDiegO, in the county of San Diegoand.Stateof California, have' invented certain new and useful Improve.`ments'in Surfacing-Machines, of'which thel v 13, pinion 14, motor15a11d shaft 16 con-l following is a specification.A p

Our invention relates tov a machine yfor surfacing blocks such as meatchopping blocks and the like and the objects ofv our invention are:first, to provide a machine of this class which may be readilydsassembledand is portable and may be easily moved from place to placeby one person; second, to provide a machine of lthis class by the use ofwhich a block may be readily surfaced so that it is level on the top`Withoutinjuring this class which vis adjustable throughoutv thus makingit applicable to different .and various sized blocks; iifth, to providea surfacing machine of thisl class in which an ordinary circular saw maybe'used and in which no Aspecial cutter is required" and sixth, toprovide a surfacing machine of this class which is very simple andeconomi# cal of construction, durable, easy to, operate, easy to installand whichwill not'readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, ourinvention consists of certain novel features of construction,combination and arrangement of partsv and portions as will behereinafter described in detail and particularly set forth in theappended claims, reference being had to the accompanying drawings and tothe characters of reference thereon which form a part of thisapplication, in which:

Figure 1 is a plan view of our device shown in position on a'block andin position 'for surfacing the,same;.F1g. 2 1s a s1de elevational viewthereof; Fig. 3 is a sec.

tional view through 3-3 of Fig. 1 onan' Specification of Letters Patent.Patented.' lua);l 17, 1921 Application 'led Augustli, 1919.' Serial No.315,066. I

' Similarcharacters of reference refer to similar parts and portionslthroughout the several views of the drawings.

The Asupports l, clamping membersr 2, track supports 3, clamps-'4, trackmembers.`

stitute theprincipal parts and portions of our surfacing machine.

4The supports 1 are 'preferably'vll'l members. f

They are provided in one end with a rality'of ratchet notches 1a andinthe middle Wlth a strut member 1b over whichy is provideda member 1cand it is secured to they f opposlte ends ofthe support 1 forming a:

truss for v strengthening Asaid support. Secured to said supports neartheir'oneends are lugs 1d which are provided With projections 1e rontheir inner surfaces which are adapted to enter the sidevof the blockwith, the lugs 1b against the same for holding them in`position.-Shiftably mounted on'.-4 i

these supports 1 near their vopposite ends are clamp members 2 which areheld in certainv relative positionl tosaid support; by means of ratchetpawls 2a shown best in Fig. 4 prvotally' mounted in said clamp memberand adapted to engage the notches 1a on the supports 1.

are provided with wing bolts 2b which extend through said clamp `membersand their lug member 2c which is also providedl with the block. Mountedat .each end of the 4aupports 1 is a right angled lug 1f. which isprolprojections 2d adapted to engage theside of vided with an internallythreaded hole f adapted to receive the threaded supports 3 and swiveledon the upper ends of these supports 3 are vtheclampmgv members 4 whichare shaped as shown best in Figs. 1

and 2 of the drawings which is adapted to clampand support the trackmember i5. It is provided with a hook portion 4a which is adapted toengagethe upper surface of the L member 5a upon vwhich the track 5 issecuredand said clamping member'is provided with an upwardly extendingmember 4b which is provided with` a wing screw 4A 85 These clampingmembers 2` the rollers 7 which are provided with beveled vgroovesconforming A to the beveled edges of the track members 5. These rollers7 are mounted on axles which are secured in Athe ends 4of the tubes-6,the `axles in one of' 'g :said 4tubes being set ecceritrically, in saidtube as shown best in Fi 5 to provide forv adjustment of' the tube reatively tothe periphery of the roller to provide for adjustably, raisingthe front edgey of the saw, tof

give it relief and to preventits' gouging in the block. These tubes 6are rigidly secured together at their opposite ends bymeans of thesuports" 8 which are secured thereto, and shlftably mounted on these tubesis the support 11 which is providedwith lugs 11 which-areshiftablymounted on the tubes 6 and with a plate portion to which the motor 15 issecured. It is provided with an up? Secured on the lower end of theshaft 16 is an annular support 12. to which is secured the circular sawor cutter12 by means of screws I2b shown best in' .Fig. 6. It will be i,noted that the weight of the carriage and motor resting on the trackholds the saw in certain relative position to the block and A that thetracks 5 are positioned relatively to the block before-starting thesurfacing operation. Swiveled in the members 8 is a vfeed screw member 9which is providedwith a hand wheel 10 on one outer end adapted tofacilitate the turning of the same.

The operation of the surfacing machine is as follows: The block isfleveled up, the supports are secured to the sides as shown best in Fig.1 of the drawings and the bolts 3 are turned positioningt e top of thetracks .5 as desired relatively to the top of the blbcks, the support 11is turned to near one side by means of the hand wheel 10 so that thecutter 12 may engage oneside of thev block, the tracks 5 being leveledso that they are positioned relatively to the block, then the motor isstarted and the rollers 7 moved' along the tracks 5, the -saw cuttinga-,groove 'in the edge of the block to theopposite side after which theportionv sawed under by the block is removed by a hatchet or other sharptool, the carriage is moved back to the opposite side, the hand wheelturned to 'cut anothei` groove on the saine level and the carriage again.pushedlacrossthe' block, out; 'ting another groove: which iscontinueduntil the entire top surface of the. lblock isi surfaced.

Though we have shown and deseribedac" lparticular construction,combinationand aiad rangement of parts and portions, we :do not wish to`bewlimited tothis particular n struction, combination and arrangementfut,

desire to includein the purview ofoui in- 'vention the construction, lcombination and i arrangement substantially as set forth intheap endedclaims.

. aving thus described our invention what weclaim as new and desire tosecure by'Let` ters Patent, is:

1. A device of the class described, including a pair of truss members,each provided 'with a block engaging member near one end` and with aclamp screw spaced therefrom and adjustabley thereon for, clamping saidtruss members to saidblock, a pair of track members disposed at rightangles thereto and adjustably supported thereon provided with beveledupper edges, a carriage provided with langed'wheels conforming to theupper edges of said track members mounted' on said tracks and movablethereon, a support shiftable longitudinally, 0n said carriage, avertical shaft journaled in said support, a cutter secured to `the lowerend 'of said shaft and'means mounted on said support connecting withsaid shaft for revolvf ing said shaft.

` 2. A device of theclass described, including a pair of truss members,each provided with a block engaging member. near one end and' with' aclamp screw spaced therefrom and adjustable thereon for clampin s aidtruss members to said block, apair o' track members disposed at rightangles thereto and adjustably supported thereon provided with beveled4upper edges, .a carriage provided with flanged wheels conforming to theupper edges of said track members mounted on said tracksk and movablethereon, a support shiftable longitudinally on said carriage, a verticalshaft journaled in said Support, a cutter secured to the lower end ofsaid shaft, means mounted on said support connecting with said shaft forrevolving said shaft and means in connection 4with said carriage foradjusting the height of one side of the carriage relatively to itssupporting wheels.'
